Feature/pre commit test integration

[thommodin]

This pull request introduces several improvements to code organization, dependency management, and developer workflow. The changes focus on standardizing import order, enhancing pre-commit and CI workflows, and making minor code cleanups for consistency and maintainability.

Developer workflow and CI improvements:

• Added new pre-commit hooks for linting, formatting, requirements export, and Docker image testing in .pre-commit-config.yaml. This includes a new docker-test hook that runs on pre-push.
• Introduced an init target in the Makefile to automate pre-commit installation and hook setup, and improved the test-image target with additional logging.
• Updated the CI workflow in .github/workflows/ci.yml to use ruff with --extend-select I, ensuring import order is checked.
• Added a [tool.ruff.lint] section to pyproject.toml to enforce import order checks (extend-select = ["I"]).

Code organization and import order:

• Standardized and reordered imports across multiple modules to comply with linting rules and improve readability, including moving pydantic and other imports to the top or grouping them logically. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16]

These updates will help maintain a consistent codebase, catch import order issues early, and streamline development with improved automation.
